In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter.
NASA is a step closer to returning astronauts to the Moon in the next five years following a successful engine test on Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The latest “hot fire” was the culmination of four-plus years of testing for the RS-25 engines that will send the first four Space Launch System (SLS) rockets into space.
A team of researchers from the University of Nebraska–Lincoln recently conducted an experiment where they were able to accelerate plasma electrons to close to the speed of light. This “optical rocket”, which pushed electrons at a force a trillion-trillion times greater than that generated by a conventional rocket, could have serious implications for everything from space travel to computing and nanotechnology.
When Elon Musk launched SpaceX in 2002, he did so with the intention of making reusability a central feature of his company. Designed to lower the costs associated with launches, being able to reuse boosters was also a means of making space more accessible. “If one can figure out how to effectively reuse rockets just like airplanes,” he said, “the cost of access to space will be reduced by as much as a factor of a hundred.”
KENNEDY SPACE CENTER, FL – At the request of the new Trump Administration, NASA has initiated a month long study to determine the feasibility of converting the first integrated unmanned launch of the agency’s new Space Launch System (SLS) megarocket and Orion capsule into a crewed mission that would propel two astronauts to the Moon and back by 2019 – 50 years after the first human lunar landing.
